Title: Ultrasonic microscope
Inventor: TOKIOKA MASAKI
IPC: G01N29/22
Filed: 1989-11-16
Abstract: PURPOSE:To facilitate the manufacture of an ultrasonic probe and to switch frequencies by optionally switching electric signals of three frequencies, i.e. the resonance frequency of a piezoelectric element and two frequencies corresponding to resonance which differ in specific wavelength with the thickness of the piezoelectric film of the piezoelectric element. CONSTITUTION:The electric signals of the three frequencies, i.e. the resonance frequency of the piezoelectric element, the frequency corresponding to lambda/4 (lambda: wavelength of sound wave) resonance, and the frequency corresponding to lambda/2 resonance are optionally switched and applied to the piezoelectric element by high-frequency pulse oscillators 13 - 15. The signals from the oscillators 13 - 15 are selected by a sent wave signal switch 16 and applied to an ultrasonic wave transducer 12 through a circulator 17. An ultrasonic wave which is excited 12 is converged 11 and emitted to a sample 20, and the reflected signal which is reflected nearby the surface of the sample 20 is passed through the circulator 17, amplified and detected by a receiving circuit 12, and then sent as a video signal to a display device 19.

Title: Display device
Inventor: YOSHIMOTO HATAAKI
IPC: G02F1/13357
Filed: 1991-08-30
Abstract: PURPOSE:To obtain a display device having high contrast and high quality by providing a means for making the light of a backlight proximate to the parallel rays of light between a display panel and the backlight. CONSTITUTION:The display panel 1 is constituted of polymer dispersed type liquid crystal, and a slit plate 4 is disposed between a means 2 for driving the display panel 1 and the backlight 3. The slit plate 4 restricts the direction of light from the backlight 3 and makes the light proximate to the parallel rays of light, and the incident angle on a polymer dispersed side liquid crystal layer 1 is made small. Since the light having the large incident angle out of the light made incident on the liquid crystal layer 1 makes a brightness level at an off-time high, the contrast is made low. By making the incident angle small by using the slit plate, the contrast is drastically made high. A plate formed by arranging thin plates with a little reflection in a vertical direction to the display panel 1 is used as the slit plate 4.
